CARBONATITE DEPOSITS (MODEL 10; Singer, 1986a)

Ore minerals may be disseminated throughout carbonatites, or concentrated in bands or zon Multiple stages of igneous activity and metasomatic replacement may have produced localized ore mineral concentrations Carbonatite complexes may include multiple stages of carbonatite dikes and veins, which cut earlier carbonatite and host rocks.

Leaching of rare earth elements from ‘Rödberg’ ore of Fen ,

Rödberg ore is a hematite-calcite-dolomite carbonatite rock type of the Fen complex deposit, that has been formed from ferrocarbonatite transformation occurred by the action of groundwater oxidizing hydrothermal solutions (Andersen, 1984, Andersen, 1987)

Ore - Wikipedia

An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit The ores are extracted at a profit from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements
